The objective of this proposed program is to design an object-oriented architecture for satellite communications management using world wide web (WWW) technology. The design will be an object oriented three-tier data base architecture based on the Java language. The architecture will consist of four parts: The monitoring subsystem, the coordination subsystem, the simulation subsystem, and the user interface subsystem. They will interact with each other as well as with the Automated Communications Management System (ACMS). The developed system will utilize the ACMS data base as its primary source of information. Two prototypes will emerge from Phase I, the coordination management system and the simulati tool. Each prototype will benefit military as well as future commercial satellite communica management systems.
